'ro GENERAL srnnn casrmes conrom'rIoN, or GRANITE our, nnmorsn eon- IORATION OF DELAWARE RAILWAY CAR DRAFT SILL Original application filed April 18, 1928, Serial No. 270,950. Divided and this application filed April 5,

1929. Serial N0. '3 52-,818.

My invention relates to railway rolling stock an consists in a novel draft sill, coupler carrier and associated structure, and the present application is a division of my applicav tion, Serial N 0. 270,950, filed April 18, 1928, and illustrating and describing a complete hopper ore car underframe in which the pres-.

ent structure is advantageously used, although also adapted for general use in cars. o-

provide an improved coupler-carrying element adapted to withstand deflection tenden-- cies caused by the bufling and pulling forces "incident to the use of heavier cars and the greater loads carried thereby.

. Another object of my invention is to provide draft sills and associated structure havi ing strength to withstand the abuse that a heavy steel hopper car loaded to capaclty with heavy material is bound, tobring upon draft gear and its mounting.

In the accompanying drawings Wl'llCh 1liustrate a selected embodiment of my inven- Figurel is a to view of the longitudinal half of one end. 0 a'hopper car underframe including my novel structure.

Figure 2 is a longitudinal vertical section taken on the center line of the underframe shown in Figure 1.

' Figures 3 and 5 are vertical sections taken on lines 3-3 and 55 respectively of Figure 1. i v Figure 4 is an end view of the striking plate, draft sills and coupler carrier.

Figure 6 is a horizontal section taken on line 66 of Figure 2.

The draft framing in the preferred form of my invention is integral with the remainder of the underframe. Each of said draft sills 7 is box-shaped in cross section with closed front ends and the sills are parallelwith the longitudinal axis of the car, being spaced to receive the necessary draft rigging. The outside walls of the draft sills 7 curve outwardly so as to merge with the front wall of the corresponding bolster 9.

"The inside walls of the draft sill merge with diagonal inembersD which assist the bolster in transmitting longitudinal forces One of the objects of my invention is to to thecenter sills C. This structure forms the subject matter of my above mentioned copending application.

The outer .ends of draft sills 7 are integrally connected by an upper web 10, having a depending flange 10a forming the striking plate, and by a channel-shaped coupler carrier member 11 which has its web 12 disposed vertically and its flanges 13 and 14 disposed horizontally and extending inwardly from the end of the car and connecting the lower portions of the draft sills 7.- Ribs 15 brace the flanges intermediate-their ends. If preferred, the coupler carrier may be made of I-be am or box shape or other desired cross section.

The inside walls of the draft sills 7 are provided with draft lugs S and T. The outside walls of the draft sills are provided with elongated openings 16 to permit insertion and-longitudinal movement of the draft gear side springs and the openings 17 in the inside walls of the sills permit insertion and longitudinal movement of the side spring shaft. The openings 18 permit insertion and longitudinal movement of the draft keys.

One draft sill 7 and the diagonally opposite draft sill 7 at'the opposite end of the car are provided with laterally extending brackets 19, integral with the sills ,7 and adapted to mount hand brake rigging (not shown). Each of these brackets extends outwardly from the draft sill and is reinforced with suitable integral uprightribs 20 connecting the bracket and the lower portion of the wall of the draft sill. i

The bolster construction and the parts at the rear of the bolster do not form part of the subject matter claimed in this application but are illustrated to show the type of underframe for whichmy draft sill, coupler carrier and associated structure are designed. They illustrate a relatively heavy underframe construction adapted to carry relatively heavy loads. These parts, however, may be altogether diiferentand the details of the structure claimed herein may be modified without departing from the spirit of my invention and I contemplate the exclusive use the same.

of such variations as come within the scope tending flanges, and a web connecting the tops of said sills and having a depending flange substantially aligned with the web of said element. I

4. In a railway car draft framing, draft sills. a channel-shaped coupler-carry ng element connecting the lower outer ends of said sills and integral therewith. and a hand brake bracket projecting outwardly from and integral with one of said sills near the end of 5. In a railway car draft framing, boxshaped draft sills each having outside and inside walls, there being elongated openings in the outer walls of said sills for insertion of a draft keys, and draft lugs integralwith the inner walls of said sills.

6. In a railway draft framing-draft sills, a channel-shaped coupler-carrying element with a vertically disposed web and horizontally disposed flanges, said element being integral with said sills and connecting the bottom of their outer ends. I

7. A- railway car draft sill having inner and outer walls, said" outer wall being provided with a horizontally extending bracket .for mounting a hand brake, there being an upright reinforcing rib connecting said bracket and the lower portion of said wall. I

S. In combination; draftsllls, a channelshaped coupler-carrying element with a vertically disposed web and horizontally disposed flanges, said element being integral with said sills and connecting the bottom of their outer ends, a web integral w th said .draft sills connecting the top of said draft sills and having a depending flange forming a striking-plate, draft lugs integral wit-h said draftsills. said sills being provided with elongated openings between said lugs'to permit insertion and movement of draft gear side spring shafts.

9. In a railway car draft framing, draft sills each having an inner and an outer wall, and a channel-shaped coupler carrier extending between said inner walls and integral therewith. J

10. Ina railway car draft'framing; draftsills} and a coupler carrier element integral with said sills and comprising a vertical web, an upper flange extending inwardly" of the 1 car, a wider lower flange extending similarly,

and ribs between said flanges intermediate said sills. p

11. In a railway car draft framing, boxsha-ped draft sills with closed ends, and a striking plate integral with said sills and comprising a horizontal web flush with the tops of said sills and a depending flange on said web flush with the ends of said sills.

12. In a car underframe, spaced draft sills, and a coupler carrier element between said sills. said element being of channel-shaped cross section wit-h its web disposed vertically.

13, In a car underframe, spaced draft sills,

and a coupler carrier element between said sills, said element comprising a. vertically disposed web with horizontal flanges extending inwardly of the underframe.

14. In a car under-frame, an integral casting comprising spaced draft sills of boxs'haped cross section connected near their, forward end by a channel-shaped coupler carrier having its web upright.

15. In a car underframe, spaced draft sills, each of said sills having spaced vertical walls, the inner walls comprising a draft gear housing. and each wall having an elongated opening for application of a draft gear side spring shaft and movement of the same longitudinally of the sill and each outer wall having 1 a larger opening for receiving adraft spring and accommodating movement of the same longitudinally of the sill. r

16. In a car underframe casting, a draft sill spaced from the longitudinal center line of said casting and-having spaced vertical walls.

the inner side of the inner wall having a draft gear stop lug and the outer wall having an elongated opening for application of a. draft gear side spring and for movement of the same longitudinally of the sill.

In testimony whereof I hereunto afiix my signature this 1stday of April, 1929.
